Nov 20, 2002· Rare Earth Element Abundances "Rare" earth elements is a historical misnomer; persistence of the term reflects unfamiliarity rather than true rarity. The more abundant REE are each similar in crustal concentration to commonplace industrial metals such as chromium, nickel, copper, zinc, molybdenum, tin, tungsten, or lead (fig. 4).

Rareearth magnets have higher remanence, much higher coercivity and energy product, but (for neodymium) lower Curie temperature than other types. The table below compares the magnetic performance of the two types of rareearth magnets, neodymium (Nd 2 Fe 14 B) and samariumcobalt (SmCo 5), with other types of permanent magnets.
Rare earth ore goes through these steps hundreds and hundreds of times, and for each new mining location, the concentration of the acids used has to be recalculated in order to target the specific impurities in the soil. To top it off, the whole process produces any number of nasty chemical byproducts and is radioactive. Rare Earth Response
